Question

0.111 mol of argon gas is admitted to an evacuated 40.3 cm3 container at 40.3 ∘C. The gas then undergoes an isothermal expansion to a volume of 513 cm3 . What is the final pressure of the gas?

Answer #1

0.15 mol of argon gas is admitted to an evacuated 40 cm3
container at 40 ∘C. The gas then undergoes an isothermal expansion
to a volume of 400 cm3
What is the final pressure of the gas?

0.10 mol of argon gas is admitted to an evacuated 40 cm3
container at 20 ∘ C. The gas then undergoes an isothermal expansion
to a volume of 100 cm3 . What is the final pressure of the gas?

0.15 mol of argon gas is admitted to an evacuated 40 cm3
container at 20∘C. The gas then undergoes an isochoric heating to a
temperature of 500 ∘C.What is the final pressure of the gas?

0.10 mol of argon gas is admitted to an evacuated 50 cm^3
container at 20∘Celsius. The gas then undergoes an isobaric heating
to a temperature of 330 ∘Celsius. What is the final volume of the
gas?

If 1.00 mol of argon is placed in a 0.500-L container at 30.0 ∘C
, what is the difference between the ideal pressure (as predicted
by the ideal gas law) and the real pressure (as predicted by the
van der Waals equation)? For argon, a=1.345(L2⋅atm)/mol2 and
b=0.03219L/mol.

If 1.00 mol of argon is placed in a 0.500-L container at 29.0 ∘C
, what is the difference between the ideal pressure (as predicted
by the ideal gas law) and the real pressure (as predicted by the
van der Waals equation)?
For argon, a=1.345(L2⋅atm)/mol2 and
b=0.03219L/mol.

A 10.09 mol sample of argon
gas is maintained in a 0.8203 L container at
301.8 K. What is the pressure in atm calculated
using the van der Waals' equation for Ar gas under
these conditions? For Ar, a =
1.345 L2atm/mol2 and b =
3.219×10-2 L/mol.
_______atm

Argon is stored in a container of volume 2 litres at a pressure
of 3 atmospheres. The amount of gas present is 0.2 mole The gas is
allowed to expand to a final volume of 4 litres while the
temperature is held constant. Find
the final pressure of the gas, and (ii) the work done on the
gas. Explain the significance of the sign of the work term.
You may assume that argon behaves as
an ideal monatomic gas. The...

A 2400 cm3 container holds 0.14 mol of helium gas at 340 ∘C
a. How much work must be done to compress the gas to 1200 cm^3
at constant pressure?
b. How much work must be done to compress the gas to 1200 cm^3
at constant temperature?

Suppose 4.00 mol of an ideal gas undergoes a reversible
isothermal expansion from volume V1 to volume V2 = 8V1 at
temperature T = 300 K. Find (a) the work done by the gas and (b)
the entropy change of the gas. (c) If the expansion is reversible
and adiabatic instead of isothermal, what is the entropy change of
the gas?
